【Abstract】 Based on real time digital simulator (RTDS),a hybrid real-time simulation method for electromagnetic transient and electromechanical transient is proposed. In the environment of RTDS/Cbuilder and by use of multithreading and doubly linked list-sparse matrix,a real-time electromechanical transient simulation program is developed. The equivalent circuit models of network interface at electromagnetic side and that at electromechanical side are put forward,and the connection between RTDS electromagnetic model and real-time electromechanical transient program is implemented,thus a hybrid real-time simulation platform is built. When the power grid containing DC power transmission is analyzed in detail,the impact of AC power system on transient stability can also be considered accurately. Simulation results show that the proposed hybrid real-time simulation method is valid and efficient.更多还原
